Abstract：
Bowl-coupler type steel tubular scaffold is usually used in bridge engineering, but it is seldom used in frame structure of cross beam slab due to the limited length module of its horizontal bar. During construction of cross beam slab in a railway station waiting room, bowl-coupler type steel tubular scaffold supporting system is adopted and the construction task is safely and successfully completed through a series of measures, such as simulative arrangement before erection, calculation of erection height and reinforcement after erection, etc.
